Abstract: The invention relates to a process for working up coke which is loaded with heavy metal and has been doped with sulphuric acid before loading. It is the object to permit large amounts of flue gas of a waste incineration plant to be freed from heavy metal in such a way that only a small amount of coke loaded with the heavy metals is obtained and can be disposed of simply and in an economical manner. To achieve this object, the invention envisages a procedure in which the coke loaded with the heavy metal from the flue gas of the waste incineration plant is passed through a reactor (1) which has at least one desorption zone (7) and is heated within the desorption zone (7) to temperatures of about 500 DEG C. For desorption of heavy metals, the coke is heated in the reaction zone (7) for a period between 10 and 15 minutes and is treated during this time with an entrainment gas (10). The entrainment gas takes up the heavy metals released during heating of the coke. The loaded entrainment gas (16) is passed, with the supply of air (23), through a stationary bed of coke (24), which is likewise doped with sulphuric acid. This coke (24) adsorbs the heavy metal from the loaded entrainment gas (16) until a high adsorption rate of the order of between 15 and 35% is reached. After reaching the adsorptivity, the coke (40) considerably loaded with heavy metals is disposed of separately. Only relatively small amounts of this coke (40) have to be disposed of and may be placed in a landfill without particular expense. <IMAGE>

Abstract: The shearing machine includes a supporting structure (2) with a longitudinal front compartment (9) for the placement of a plate (L) to be cut and a vertically oscillating cutting blade (10) arranged above the compartment. The blade is composed of a transverse portion (11) and of a longitudinal portion (12) which substantially form a right angle between them and are suitable for selectively interacting with the plate to be cut, so as to perform a transverse cut during a first part of the descent stroke and a longitudinal cut during a second part of the stroke. The shearing machine includes a pair of fixed guiding surfaces (40, 41) which are suitable for vertically pulling apart the adjacent edges of a transverse cut (46) upon the advancement of the plate parallel to the transverse cut. By means of these guiding surfaces it is possible to impart to the plate any number of further advancement steps and of transverse aligned cuts without interfering with the supporting structure of the shearing machine before performing a final longitudinal cutting of the plate.

Abstract: The invention provides a method and means for securing card-clothed "tops" to the flats of revolving flat-type carding machines, which obviates the necessity for specialist machines used for securing clipped "tops" to the flanges of the flats. This is of particular advantage where the spinning mill is geographically remote. 
     The method employs a special type of "top" clip (52, 54; 82, 84; 112, 114) which, besides being preformed to engage with the bottom side of the "top" as is usual, also has an inward hooked formation (60, 116) along its upper longitudinal edge. In addition, various kinds of tensioning elements (62, 64; 90, 100; 86, 88; 118, 120, 128) are provided, each of which is engageable with the hooked formations on the clips, and is resiliently loaded, so that in the assembled condition, it causes the clips to pull the "top" tightly into engagement with the flanges of the flat.

Title: Arginine antagonists for inhibition of systemic hypotension associated with nitric oxide production or endothelial derived relaxing factor
Inventor: KILBOURN ROBERT G
IPC: A61K31/00
Filed: 1990-09-13
Abstract: A method for prophylaxis or treatment of an animal for systemic hypotension induced by internal nitrogen oxide production. The method involves administering a therapeutically effective amount of certain arginine derivatives to inhibit nitrogen oxide formation from arginine. Preferably N<G>-substituted arginine or an N<G>,N<G>-disubstituted arginine (having at least one hydrogen on a terminal guanidino amino group replaced by another atomic species) is administered to an animal possibly developing or already having such induced systemic hypotension. The arginine derivatives are preferably of the L configuration and include pharmaceutically acceptable addition salts. Prophylaxis or treatment of systemic hypotension in a patient which has been induced by chemotherapeutic treatment with biologic response modifiers such as tumor necrosis factor or interleukin-2 may be accomplished. Treatment of an animal for systemic hypotension induced by endotoxin, i.e., septic shock may also be accomplished by treatment with the arginine derivatives.
